Does anyone have a good method to determine how much length moulding to order? Specifically, how best to tell the supplier how much you want without getting too much (sometimes WAY too much). I think the metric system contributes somewhat to the problem because with some suppliers, if you order 10 feet, they will send 2 three meter sticks (19.7 ft.) We use about 9 different suppliers and most of them don't have a "typical" length. Last week, I thought I had it covered when I needed 17 feet, ordered 18, and received 24. Is there an easier way than calling each time to find out the stock length of a particular moulding? Of course we order chops when appropriate but I guess determining that effectively is another matter!
